GEORGE D. HARDER, OF COBLESKILL, NEW YORK.

sPEcIFIcA'rroiv forming part of Letters Patent No. 653,474, dated July10, 1900.

Application filed May 29, 1900- To all whom it may concern:

.Be it known that I, GEORGE D. HARDER, a citizen of the UnitedStates,residin g at Cobleskill, Schoharie county, New York, haveinvented certain new and useful Improvements in Silos, of which thefollowing is a specification.

My invention relates to silos, and is an improvement upon the inventiondescribed in Letters Patent of the United States granted to me on the27th day of June, 1899, No. 627,732. The silo therein described, whichis round and comprises a series of vertical staves held together by ironhoops, has in its walls, extending throughout the length thereof, anopening through which the ensilage is dis-' charged. This opening isclosed by a series of removable door-sections which slide in guidewaysprovided by reinforcing-pieces overhanging the outer edges of theopening and overhanging pieces at the inner edges of the opening. Thehoops or bands in the form of silo which has been patented to me runbeneath the reinforcing-strips and find bearings at the outer edge ofthe wall of each opening. In the present improvement I have constructedthe brace-pieces, which extend between the edges of the opening in thesilo, with guides for the hoops, which serve to hold the parts of thehoops which span the opening away from the door-sections. The inventiontherefore includes means for guiding the hoops at each side of theopening in the silo, and it further includes the construction of thebrace-piece, which may provide such guides.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a detail elevation showing one brace spanning the opening inthe silo. Fig. 2 is a detail plan view, parts being shown in section.

In the drawings but a section of the front part of the silo is shown.The vertical staves of which the body of the silo is constructed areshown at 1, the opening in the silo through which the ensilage isdischarged at 2, and the reinforcing-strips at each edge of the openingat 3. The door-sections 4 are guided, as in my former case, in ways 5,formed between the overhanging portions of these strips and Serial No.18A37. (No model.)

the backing-strips 6. Brace-pieces span the opening 2 at intervals,which are provided with shoulder portions 7, abutting the edges of thereinforcing-pieces 3. The main portions 8 of the braces are intended toprovide steps or rungs by which a person may ascend the silo to enterthe same at any point. In the construction shown herein the shoulderportions of each brace are provided with depending portions 9, providedwith guidingopenings 10, through which the hoops 11, which encircle thesilo, are guided. As shown herein, each reinforcing-strip is providedwith an opening 12 in line with the opening 10 in the abutting portion9,whieh provides a guide for the hoop; but dependence is not placed onthese openings 12 in the strips 3 to hold the part of the hoop spanningthe opening 2 away from the door-sections. The bracepieces, however,being heavy castings, the openings 10, provided therein, serve thispurpose admirably.

It will be understood that the brace-pieces may be made of any suitablematerial. It will also be seen that by elongating the ends of thebrace-pieces, as at 9, either above or below or on both sides of theline of the main portion 8 a longer bearing is provided against theshoulders of the reinforce-pieces.

I claim 1. The combination with a round silo having an opening in thewall thereof, hoops en= circling the silo and spanning said opening, anda sectional door closing the opening, of means for guiding the hoops ateach side of said opening to hold the spanning portions of said hoopsaway-from the door-sections, substantially as described.

2. The combination with a round silo having an opening in the wallthereof extending throughout the length of the same and hoops encirclingsaid silo and spanning the opening, of braces extending between theedges of said opening, said braces providing guides for said hoops,substantially as described.

3. The combination with a round silo having an opening in the wallthereof extending throughout the length of the same, reinforcing-stripsoverhanging the edges of said opening, door-sections for closing theopening, a

' brace-bar spanning said opening having In testimony whereof I afiix mysignature shoulder portions abutting the strips, hoops in presence oftwo witnesses.

encircling the silo and spannin said opening, and depending portionsintegral with the GEORGE HARDER 5 braces having guide-openings throughthe XVitnesses:

same for the hoops, substantially as described. l
